Patent JP-H08111976-A (JP)
Title: Voltage converting circuit
Inventor: NAKAMA AKIRA
IPC: H02M3/155
Filed: 1994-10-07
Abstract: PURPOSE: To obtain a highly efficient multi-output voltage converting circuit which is simplified in circuit configuration by driving a boosting switching element at one voltage level of driving signals and dropping switching element at the opposite voltage level. CONSTITUTION: An FET 6 outputs voltages V1 and V2 to terminals 21 and 22 when the driving signal(DS) of a control section 3 is 'H'. Another FET 12 outputs a negative voltage V3 to a terminal 23 when the DS is 'L'. At the time of stabilizing the V3, a delay circuit composed of a resistor 9, diode (DD) 10, and capacitor (CS) 11 and a delay circuit controlling section composed of a DD 16, transistor(Tr) 15, and DD 14 change the duty ratio of driving signals inputted to the FET 12. Namely, the delay circuit does not operate when the DS is 'H' or when the DS is 'L' and the voltage V3 becomes lower than the set voltage of the DD 16. When the voltage D3 becomes higher than the set voltage of the DD 16, on the other hand, the Tr 15 is turned on and the CS 11 is charged, and then, the turning-on time of the Tr 12 becomes slower. As a result, the turning-on period of the Tr 12 is shortened.

Title: Designing method of interconnection of integrated circuit
Inventor: HIROKAWA ERI
IPC: H01L21/82
Filed: 1991-10-17
Abstract: PURPOSE:To reduce a chip area, to perform a high-speed processing operation, to guaranteee a 100% interconnection, to save a memory space and to reuse the result of an interconnection passing over a macro by a method wherein a net which is passed over the macro is extracted at each macro on the basis of an approximate interconnection route and the interconnection passing over the macro is executed. CONSTITUTION:When a layout inside a macro D out of macros is changed in a chip which has been laid out, its interconnection is used as it is in a macro E because an interconnection passing over the macro has already been executed. The interconnection passing over the macro is executed only in a macro F which has been changed. At this time, the interconnection is executed by using an interconnection layer which has not been used when the layout inside the macro is designed. The difference from an original net list is processed with reference to a net which has been successful, and a net list between macros is found. An interconnection inside a channel is executed to a pin pair which has failed to pass over the macros by means of a layout on a chip level. Consequently, the processing time of the title method can be halved as compared with an inter-connection where the position of a macro has been fixed to the chip as a whole.

Filed: 1987-10-26
Abstract: PURPOSE:To ensure the running stability during cornering by providing a compensating means for compensating a signal for driving an engine output regulating member, in the output power lowering direction when the steering speed exceeds a predetermined value. CONSTITUTION:A detecting means A detects an accelerator manipulation degree, and a computing means B computes a signal for a driving means E in accordance with thus detected accelerator manipulating degree so as to electronically control an engine output power regulating member F. In this phase, a speed detecting means C detects a steering speed, and when thus detected steering speed exceeds a predetermined value, a compensating means D compensates the signal for the drive means E in the output power lowering direction so as to control the engine output regulating member F in the output power lowering direction. As a result, it is possible to ensure a running stability during cornering.

Title: Compressor with rolling piston
Inventor: SAITO KENICHI
IPC: F04C29/04
Filed: 1990-10-05
Abstract: PURPOSE:To enhance the operating performance of a compressor and lubricate different sliding parts by installing a compressing means above the surface level of the lubricant, and furnishing an oil supply means to supply lubricant to the space bounded by blades. CONSTITUTION:Rolling piston 5b of a compressing means 4 is rotated by a driving means 3, and fluid flows into the compression chamber 5c via a suction path and is compressed. The compressed fluid is discharged from a discharge path to the internal space 2a of the casing 2. Because the compressing means 4 is positioned above the surface of the lubricant 0, the compressing means 4 is not immersed in the lubricant 0 at high temp., which suppresses drop of the density to be compressed in the compression chamber 5c caused by heat affection from the lubricant, and it is possible to enhance the volume efficiency in the compressing motions. The lubricant 0 can be supplied by an oil supply means 13 to the space C: bounded by blades 5g, and various sliding parts of the compressor body 4 can be lubricated.

Title: Manufacture of plate-shaped ba ferrite granular powder
Inventor: KATAMOTO TSUTOMU
IPC: H01F1/11
Filed: 1985-11-28
Abstract: PURPOSE:To form plate-shaped Ba ferrite granular powder whose granules are thick (in the C-axis direction of crystal) and are separated one by one, by adding a specific amount of Ti compound and fatty acid salt in advance to alkaline aqueous solution containing Ba ions and Fe(III) to regulate thickness of the plate-shaped Ba ferrite granules produced at a specified temperature. CONSTITUTION:Alkaline aqueous solution containing Ba ions and Fe(III) is processed by water and heat within the temperature range of 200-300 deg.C. Then, Ti compound of 1-10mol% in Ti conversion to Fe(III) and fatty acid salt of 5-200wt% to Fe(III) are added in advance to the alkaline aqueous solution containing Ba ions and Fe(III), to regulate thickness of produced plate-shaped Ba ferrite granules. Reactive temperature below 200 deg.C makes it hard to produce the plate-shaped Ba ferrite granules, on the other hand, the temperature above 300 deg.C causes a risk of being unable to maintain safety in the device. Adding amount of Ti compound under 1mol% to Fe(III) makes it hard to obtain thick plate-shaped Ba ferrite granules, on the other hand, the amount above 10mol% is undesirable because of saturated magnetic flux density decreases due to a fall in purity.

Title: Printing controller in printer
Inventor: AIUCHI SHIGERU
IPC: B41J2/30
Filed: 1991-10-17
Abstract: PURPOSE:To carry out a sharp copying on all printing paper while preventing the break of cover paper by a method wherein when a recording medium is judged to be thick by the detection result of a recording medium thickness detection means, a printing head drive means is driven. CONSTITUTION:A CPU 44 successively compares the printing positions of printing characters read from a line buffer 47 using a program. The first column and the second column are compared with each other to the last column in order. When the presence of printing information on both the columns is found as the result of the comparison, either of the printing information is deleted, and the remaining printing information is developed on a printing buffer 48. In this manner, if the printing pressure of a printing pin is increased for making printing on all the stacked paper, the break of cover paper can be prevented because of the absence of continuous printing dots.
